Solinst CMT® Multilevel Systems provide a cost effective solution for identifying and monitoring leaking underground storage tank (LUST) sites. They monitor multiple depth-discrete zones in a single borehole, providing complete data sets that quickly identify sites that pose a threat to down-gradient receptors, and those that can be closed with no further action. With strong political… Continue Reading »
The 3-Channel CMT® Multilevel Monitoring System is ideal for direct push installations, as it is only 1.1″ (28 mm) in diameter. Often with these installations, the annulus available is too small to accurately place sand and bentonite layers for isolating the monitoring zones. Therefore, bentonite cartridges (spring and pre-formed) have been developed to give reliable seals between… Continue Reading »
Certified CMT Installer Michael Early, of ZEBRA Environmental, Tampa, a company specializing in direct push sampling and probing services to consulting firms, recently installed three multilevel groundwater monitoring systems in Pinellas County, Florida. The purpose of this phase of their study is to assess the possible extent of chlorinated solvents in shallow sandy sediments at each site…. Continue Reading »

The CMT System (Since 1999) CMT offers in-field design flexibility, low cost and is easy to install. The number of monitoring ports, port locations, install depths, and monitoring strategy, can all be accommodated and designed right in the field. The single tube offers effective sealing.The 7-Channel is 1.7″ (43 mm) and the 3-Channel is 1.1″… Continue Reading »
White Young Green Environmental Limited (WYG) is an experienced environmental consulting firm operating in the United Kingdom. WYG was given the task of developing a cost effective means to isolate and reliably sample groundwater quality, and obtain hydraulic head data from various zones, in a complex geological setting, to give detailed vertical gradients. The investigation… Continue Reading »
Contaminants were identified in the subsurface at Rhine Main Air Base, Germany, in a sand and gravel aquifer. The contamination was complex due to two separate sources: a fire training pit, and a former gas station that had leaked various compounds, including BTEX, TPH, PAH, and TCE. The aquifer extends from 7 m up to… Continue Reading »
Solinst is delighted to announce another installation of the New Narrow 3 Channel CMT (Continuous Multichannel Tubing) Multilevel System using bentonite cartridges. The cartridges are designed to seal the interval between monitoring zones and are ideal for direct push applications where the annulus between the CMT installation and the drilled hole is too small to accurately… Continue Reading »
Since 2002, Solinst has been working with STS Consultants in Green Bay, Wisconsin to provide a total of four Waterloo Multilevel Systems selected to monitor a chlorinated compound release. The release was from a forest products company and occurred decades ago. Chlorinated compounds have permeated the saturated and unsaturated zones and are present in both the overburden… Continue Reading »
